Question

我有一个简单的Python脚本，粘贴在下面：

import sklearn
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.neighbors import KNeighborsClassifier
from sklearn import metrics

def get_average(arr):
    return sum(arr) / len(arr)

def get_median(arr):
    arr = sorted(arr)
    listlength = len(arr) 
    num = listlength//2
    if listlength%2==0:
        middlenum = (arr[num]+arr[num-1])/2
    else:
        middlenum = arr[num]
    return middlenum



iris = load_iris()
sklearn.utils.Bunch

# Data
X = iris.data
# Classes
y= iris.target
# Split data
X_train, X_test, y_train, y_test = train_test_split (X,y,test_size = 0.2, random_state = 4)


scores = []
best_k = 0
best_score = 0
for k in range (1,30):
    knn = KNeighborsClassifier(n_neighbors = k)
    knn.fit(X_train, y_train)
    y_pred = knn.predict(X_test)
    score = metrics.accuracy_score(y_test, y_pred)
    if score > best_score:
        best_k = k
    scores.append(score)
    # print(scores)

print("Your scores were: ", scores)
print("The best k value was: ", k)
print("The average score was: ", get_average(scores) * 100)
print("The median score was: ", get_median(scores) * 100)

我正尝试将其编译为没有Python的老板的.exe文件，然后在他的计算机上运行它。在使用gcc和Java使用javac之前，我只编译过C和C ++代码。

我尝试使用pyinstaller模块来编译.exe。但是，当我运行.exe

时遇到以下错误

我尝试了以下步骤：

升级点（python -m pip install --upgrade pip）
每个this post升级setuptools（python -m pip install --upgrade setuptools）
重新编译
删除dist，然后重试

我确实制作了另一个示例文件，

print("hello world").py

编译并运行正常。

我也尝试过重新编译文件，并在我第一次错过的编译器中发现了许多WARNING消息。

Answer 1

实际上pyinstaller不支持sklearn的导入，请参阅Pyinstaller Supported Packages，经过多次研究，合适的答案似乎是hook，但是我没有花足够的时间来解释它正确地

相反，对我有用的是，手动导入所需的lib /方法，它应该像这样：

编辑

将此添加到导入列表：

import sklearn.neighbors.typedefs

运行pyinstaller yourfile.py

即使有警告和错误消息，也要等到它结束。

然后我们需要在\\dist\\test\\sklearn\\datasets中创建两个目录：

data，您需要在其中复制并粘贴iris.csv中的C:\Users\{your_name}\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\sklearn\datasets\data
descr，您需要在其中复制并粘贴iris.rst中的C:\Users\{your_name}\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\sklearn\datasets\descr

请注意，这是我的python版本（Python37-32）

希望有帮助

pyinstaller无法使用sklearn编译导入的模块
